WICK-CARRIER FOR CENTRAL-DRAFT LAMPS.

SPECIFICATION forming part of Letters Patent No. 492,585, dated February28, 1893.

Application filed August 1, 1892.

To all whom it may concern:

Be it known that I, WILLIAM A. PENFIELD, of Meriden, in the county ofNew Haven and State of Connecticut, have invented a new Improvement inWickCarrier's for Central- Draft Lamps; and I do hereby declare thefollowing, when taken in connection with accompanyin g drawings and theletters of reference marked thereon, to be a full, clear, and exactdescription of the same, and which said drawings constitute part of thisspecification, and represent, in-

Figure 1, a viewin vertical section of a lamp provided with awick-carrier constructed in accordance with my invention. Fig. 2, atransverse section on the line a;m of Fig. 1, showing the wick-carrierin plan, and the central-draft tube and the wick in section. Fig. 3, abroken view, partly in vertical section, and partly in side elevation,showing the action of the burner in preventing the release of the wickby arresting the upward movement of the wick-carrier before that cantake place. Fig. 4, a similar view, showing the burner removed, and thewick-carrier raised, and its jaws disengaged from the wick by theengagement of their tripping-arms with the lower face of the top of thefount.

My invention relates to an improvement in wick-carriers forcentral-draft lamps, the object being to produce a simple, cheap,convenient and effective device, constructed so as not to release thewick until the burner has been removed from the lamp-fount.

With this end in view, my invention consists in a wick-carrier havingcertain details of construction and combination of parts as will behereinafter described and pointed out in the claims.

The lamp-fount A, burner B, and centraldraft tube C, are of ordinaryconstruction, the latter being provided in the usual manner with acylindrical wick D.

As herein shown, the frame of the wick-carrier is semi-circular in formand constructed at its ends with bearings E, E, respectively receivingtwo pivotal jaws F, F, which turn upon them in the same vertical plane,and which are located directly opposite each other on opposite sides ofthe draft-tube, and so as to engage with the wick at opposite pointsSerial No. 441,843. (No model.)

thereon. These jaws are tapering in form, being widest at the top, wherethey are furnished with inwardly projecting teeth, and conformed to thecurvature of the wick, with which their teeth engage. The said jaws areformed with outwardly projecting trippingarms F, F, having cam-likeformations at their ends for engagement with the inclined lowerv face ofthe top of the fount A, as shown by Fig. 4 of the drawings. Normally thejaws are urged inwardly toward each other, and thus against the wick, bymeans of a semicircular spring G, made of wire, and having its endsengaged with the lower faces of the inner ends of the tripping-arms F F,which are thereto notched as at f, as shown by Figs. 3 and 40f thedrawings. This springis placed undertherequiredtensionbyhavingitscentral portion passed under the central, outwardlyprojecting arm E of the frame, and over two small grooved lugs e, e,formed on the frame at equi-distant points from the opposite faces ofthe said arm, E As herein shown, the extreme ends g, g, of the saidspring G, are bent upward, as best shown in Fig. Land hold the jaws inplace on the bearings E, E, the jaws being thus held against theshoulders e, e, formed on the frame just inside of the said bearings. Iwould have it understood, however, thatif preferred, I may employ asingle spring otherwise arranged, for operating the jaws, or I mayemploytwo independent springs therefor. The arm E before mentioned, projectsoutwardly and downwardly from the center of the frame and is furnishedat its extreme outer end with a vertical sleeve e the top of the fount,in line with the guidetube H, forms a bearing for the short leg of thedraw-bar, the loop at the upper end where- It will be understood thatinthe normal operation of the lamp, the jaws will be engaged with thewick, so that when the carrier is raised and lowered, the wick will becorrespondingly moved upon the draft tube 0.

p The carrier, however, is arrested by the engagement of its jaws withthe lower end of the burner as shown by Fig. 3 of the drawings,

before its tripping arms are brought into contact with the inclinedlower face of the top of the fount, so that the wick is prevented frombeing released until after the burner has been removed from the lamp.That done, the carrier may be elevated still higher, as shown by Fig. 4of the drawings, when the trippingarms of its jaws engage with the topof the fount, and turn the jaws outwardly on their pivots until they aredisengaged from the neither are the particular forms in which theseparts are shown herein. I would therefore have it understood that I donot limit myself to the exact construction and combination of partsherein shown and described, but hold myself at liberty to make suchchanges and alterations as fairly fall within the spirit and scope of myinvention. I am aware, however, that a prior patent shows a wick-liftemploying two spring-actuated gripping-jaws hung opposite each other ina horizontal frame, carried by the draw-bar, and each having anoutwardly projecting tripping-arm by means of which the jaws are turnedon their pivots and disengaged from the wick when the device issufiiciently lifted by the draw-bar.

I am aware that it is old to make a bowed draw-bar having a long legwhich is passed through a vertical tube mounted in the fount,

and a short leg to which a wick-holder is attached.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. In a central-draft lamp, the combination with the fount and thedraft-tube thereof, of a guide-tube mounted in the fount and projectingthrough the same at its upper and lower ends; and a wick-carriercomprising a frame constructed with a central, outwardly projecting armterminating in a sleeve which slides up and down over the saidguide-tube, and thus steadies the wick-lift, two springactuated jawspivoted to the said frame at points thereon opposite each other, andeach provided with an outwardly projecting tripping-arm, and a boweddraw-bar having its short leg attached to the said arm of the frame at apoint between the sleeve and the body thereof, and having its long legpassed through the said guide-tube in which it has bearing and plays upand down, substantially as set forth.

2. In a central-draft lamp, the combination with the fount and thedraft-tube thereof, of a guide-tube mounted in the fount and pro jectingthrough the same at its upper and lower ends; and a wick-carriercomprising a semi-circular frame having a bearing at each of its ends,and constructed with a central, outwardly projecting arm terminating ina sleeve, two jaws respectively mounted on said hearings, to turn in avertical plane, and each provided with an outwardly projectingtripping-arm, a semi-circular spring applied in tension to the frame,and having its ends engaged with the jaws, for turning them inward, anda bowed draw-bar having its short leg attached to the said arm of theframe, and its long leg passed downward through the guidetube whichpasses through the sleeve of the said arm, substantially as set forth.

In testimony whereof I, have signed this specification in the presenceof two subscribin g witnesses.

WILLIAM A. PENFIELD.
